Boto3 updating multiple values

Question

in the boto3 documentation updating an item is described by this example:

table.update_item(     Key={         'username': 'janedoe',         'last_name': 'Doe'     },     UpdateExpression='SET age = :val1',     ExpressionAttributeValues={         ':val1': 26     } ) 

But what am i supposed to do, if i want to update several values of the item. I couldn't find any information on this. Can anybody help? Thank you!

EDIT:

Ok, it seems to work like this, can anybody confirm wether this is the right way. Just to be sure i'm not doing anything totally wrong here.

table.update_item(                     Key={                         'id': item['id']                     },                     UpdateExpression='SET value1 = :val1, value2 = :val2',                     ExpressionAttributeValues={                         ':val1': someValue1,                         ':val2': someValue2                     }                 ) 

Thanks!

Answer 1

Yes, that's the way to do. Even many actions can be done in single expression as shown here. For ex: multiple 'PUT' and 'DELETE' in single expression.
